    I think you got it! :facepalm:

    I thought Kosmochlor was the other name of Maw sit sit and in fact, it is the black component in it!
    from there:
    https://geology.com/gemstones/maw-sit-sit/
    Maw sit sit: "Maw sit sit is not a jade. Instead, it is a metamorphic rock composed mainly of kosmochlor, clinochlore, chromian jadeite, and albite, with small amounts of eckermannite, chromite and other minerals."

    Kosmochlor:
    from there:
    https://en.wikipedia.org/wiki/Kosmochlor
    Kosmochlor is a rare chromium sodium clinopyroxene with the chemical formula NaCr3+Si2O6.

    The name is from German kosmisch, for its occurrence in meteorites, and the Greek chlor, for green.[3] It was first reported in 1897 from the Toluca meteorite, Jiquipilco, Mexico.[1]

    It occurs as a major constituent of some jadeitites and as an accessory mineral of some iron meteorites. Associated minerals include cliftonite (graphite), chromian diopside, troilite at Toluca; daubreelite, krinovite, roedderite, high albite, richterite, chromite (Canyon Diablo); and jadeite, chromite and chlorite (Burma).[2]

    I think that’s it too but I don’t think the stone should be identified as that without professional confirmation. That’s just my opinion and I’m really conservative on how people list stuff. I don’t see the piece as warranting money for a gemologist so if a couple of pictures to mineralogy museum departments don’t yield a definitive answer and the piece is being sold my opinion is that it should be sold as coral and green stone.

    You may also want to double check the silver content, before advertising as something specifically.
